Pentium 4 moves house - New Socket and Platform surfaces from Intel - Benchmarks - Video and Audio Encoding

Mainconcept Encoder 1.4.2


Mainconcept is a DV conversion utility to convert DV files into MPEG Layer 2 (DVD) quality video files. We use a 1.2GB test file and convert it into a MPEG-2 video at 720x576 at 25fps with stereo sound and calculate the time each system takes to encode the file, the less the time, the better



Here the newer CPU and chipsets don't get a good a run due to the lack of optimisations for SSE3 and DDR-2 at this stage.




XMPEG is a high quality converter based on lossless MPEG/AC3 decoders. It decodes MPEG1 (Audio & Video) and MPEG2 streams and offers you the possibility to re-encode them in the format you want. It exports video and audio frames through an Adobe Premiere interface. To keep the maximum quality of your film, it integrates HQ Bicubic (0, 0.75) and Bessel (for audio) filters.


For this we used the same file for Mainconcept, however, this time we used XMPEG to convert the file into a MPEG-4 or DIVX video.



Here with SSE3 optimisations we see the new P4 take a good hit at the encoding tasks.


Lame MP3 Encoder


Lame MP3 is an audio encoding utility that can turn your large wav files into simple MPEG-3 MP3 files. For this we used a 200MB wav file and converted it to MP3 with 128bit 44kHz.



Again, like Mainconcept, no SSE3 and DDR-2 optimisations make for a slower experience.
